The careful acoustic design, no compromise transducers, and a unique, composite cabinet design make the HDL 20-A the preferred tool of many professionals. Perfect in live sound reinforcement and reliable installed situations. The HDL 20-A is the ideal choice when line array performance is needed and a fast and easy set-up is a must. The system is powered by a 1400 Watt Peak Power 2-way digital amplifier, and sound is processed by a powerful DSP. The processing includes cluster and HF projection correction and special new presets for indoor and high-curving situations. The system features state-of-the-art RCF transducers, two powerful 10” for a solid bass reproduction, and a large format 3” voice coil compression driver to deliver vocal clarity and high definition with an incredible dynamic. The HDL 18-AS is the ideal flyable bass complement for the HDL 20-A array system.
